Abstract

Patente de Invenção: <B>"MICROCáPSULA QUE CONTéM MATERIAL DE NúCLEO, E MéTODO PARA A SUA PRODUçãO"<D>. Trata-se de uma microcápsula que contém material de núcleo e uma parede de cápsula, na qual a parede de cápsula da microcápsula compreende: Organopoliossiloxano sintetizado através da policondensação de um ou mais compostos representados pela fórmula geral (II): R~ n~Si(OH)~m~Y~ (4-m-n)~ (II) na qual m representa um número inteiro positivo de 1 a 4; n representa um número inteiro positivo de 0 a 3; m + n ( 4; R representa um grupo orgânico no qual um átomo de carbono é ligado diretamente a um átomo de silicone, e quando n é maior do que 1 cada um dos grupos R pode ser o mesmo ou diferente; e Y representa pelo menos um gr4upo selecionado do grupo que consiste em um grupo alcóxi, hidorgênio e um grupo silóxi, e quando (4-m-n) é maior do que 1 cada um dos grupos Y pode ser o mesmo ou diferente; contando que o composto (B) comprenda pelo menos um composto de fórmula (II0 na qual m = 2 ou 3 e pleo menos um grupo R tenha afinidade com pelo menos uma dentre uma fase contínua e uma fase dispersa; um método para produzir a microcápsula; e um uso da microcápsula, por exemplo, para cosméticos.Invention Patent: <B> "MICROCapsule that contains nucleus material, and its production method" <D>. It is a microcapsule that contains core material and a capsule wall, in which the capsule wall of the microcapsule comprises: Organopoliosiloxane synthesized through the polycondensation of one or more compounds represented by the general formula (II): R ~ n ~ Si (OH) ~ m ~ Y ~ (4-mn) ~ (II) in which m represents a positive integer from 1 to 4; n represents a positive integer from 0 to 3; m + n (4; R represents an organic group in which a carbon atom is directly attached to a silicone atom, and when n is greater than 1 each of the R groups can be the same or different; and Y represents at at least one group selected from the group consisting of an alkoxy group, a hyidorogen group and a siloxy group, and when (4-mn) is greater than 1 each of the Y groups can be the same or different; provided that the compound (B) comprises at least one compound of formula (II0 in which m = 2 or 3 and at least one group R has affinity for at least one between a continuous phase and a dispersed phase; a method for producing the microcapsule; and a use of the microcapsule, for example, for cosmetics.
